Article 134. General article:
Though not specifically mentioned in this chapter, all disorders and neglects to the prejudice of good order and discipline in the armed forces, all conduct of a nature to bring discredit upon the armed forces, and crimes and offenses not capital, of which persons subject to this chapter may be guilty, shall be taken cognizance of by a general, special , or summary court-martial, according to the nature and degree of the offense, and shall be punished at the discretion of that court.
—10 U.S.C. § 934 (effective 2008)
Point 3
Article 134 encompasses offenses that are not specifically listed in the Manual for Courts-Martial. Note that Article 134 is often considered to be a "catch-all" for various offenses that aren't necessarily covered by the other articles in the UCMJ, including adultery and disloyal statements.
